IMPROVEMENT IN GRAINBINDERS.

Specification forming part of Letters Patent No. 124,020, dated February 27, 1872.

Nature of the Ewout/ion.

This invention consists in the construction and arrangement of the parts, as hereinafter described.

General Description.

In the drawing, Figure l is a perspective View of my improved machine; Fig. 2, a vertical section of the rear part of the machine,

showing specially the arrangement for twisting the wire; Fig. 3, a bottom view of the "same, Fig. 4, a view of the curved arm and spool arrangement; Fig. 5, the end of the curved arm; Fig. 6, the caster-wheel to the rake-head; Fig. 7, one of the hook-heads or bea-rings of the cams; Fig. S, one of the cams and its shaft; Fig. 9, the arrangement for disconnecting the gears. j

Arepresents the platform of a harvester, and B the rake. To the heel of the rakeare attached arms a, which are connected by a collar, b, that slides freely on the way C. This way is simply an iron rod. A pitman, D, is jointed to the collar, and connects the rakehead with a long crank-arm, E, fixed to shaft c.' The forward-and-backward rocking motion of this crank gives the proper sweeping niot'ion to the rake. A fixed lug, d, is attached on the under side of the head of the rake, and to this is jointed an arm, F, holdin g a casterwheel, j'. This wheel runs back and forth upon a rail, G, on the rear of the platform, as clearly shown. At the extreme of motion in each stroke of the rake, the wheel turns round or changes position, so as to drag behind. In goin g forward to rake the grain, the rake stands lower, caused by the upper end of the clevis dragging higher under therake-head; but in going backward, it stands higher, to sweep over the table, by reason of .the top of the clevis turning under a shoulder, d', Fig. 6, under the rake-head.

The binding arrangement is as follows: H

is a rock-shaft, having at one end the bevelgear l meshing into pinion 2. At the opposite end of the shaft of the pinion 2 is a doubletoothed gear, 3, which receives motion, by chain 4, from any desired power. This chain and wheel are peculiar in their construction, thel chain being made up of links g g, with crosslngs h h jointed between them. The longitudinal links of the chain strike into the central groove j of the wheel, while the cross-lugs fit into the teeth t' t' on the opposite sides of the central groove. A secure connection is thus attained\vliich is essential in machinery like this. On the main shaft H are situated four cams, I, J, K, and L, whose object will presently. be explained, also, at the inner end, a crank, 7c, whose pin rests in a slot of connecting-rod l. This crank by its revolutions irnparts a reciprocating or vibrating motion to the rake-crank E through the medium of gears 5 6 and shaft c. M represents a curved arm,

which'carries the wire from spool N through eyes m m to the point O, which is jointed at n to the main arm. The wire passes through an eye in this point, and enters thence the twisting-wheel U, as will presently be described. The rear or base end of the curved arm is sustained by two shafts, o p, which pass loosely through it, and also by a brace, q, fastened to the shaft p. The ends of shaft o rest in boxes r r, while p is sustained by arms s s at its ends, which arms rest on shaft o. The arm s is of right-angled form, the part t having a crankpin, which enters a slot, u, of cam I. This slot is of such form that it will operate the arm s t to throw the curved arm M down to embrace the bundle of grain-to be bound at the proper time, and then release it when bound. For this purpose the Ina-in portion of the slot is circular and the other part is angular, and the angular part is left in the form of an open space, u', which, whenit reaches the crankpin, will allow a quick reaction ofthe arm s t, caused by the spring v on its under side connecting it with the platform. This spring throws the arm suddenly downward, and thus as quickly removes the curved arm M from contact with the bundle of grain it has held. The rear side of the curved arm M has a stop, e, which prevents it-s being thrown too far back. A compresser, P, extends from side to side of the arm M inside, and slides thereon by means of clasp-lips w w. It has a central shaft, w, and a spring, y, on top, which forces it down. The object of this compresser is to act in conjunction with the arm M to hold the bundle of grain firmly in place while it is being bound,y which it does by pressing down directly on top the mass. Q Q are two arms, which are secured on opposite sides of the box It, inclosing the twisting machinery, being cannected by a shaft, z, which passes through the box. The shaft z has a short crank, a', to which is jointed aconnectin g-rod, S, which extends back to shaft H, and has a slotted or hook-shaped head, b', which embraces the cam J, which thus throws it forward, and thus elevates the arms. The reaction ofthe arm is producedby a spring, c. These arms, when thrown down, strike into slots d d in the platform, to be out of the way ofthe grain sweeping over them. WV hen a sufticient quantity has collected, they are raised by the action of a cam, and deposit the grain under the curved arm M, which then descends upon it. The grain is prevented from being thrown upward in the reverse motion of the arms Q Q by means of a fixed guide, T, of a form similar to the curved arm M, which guide extends out between said arms Q Q, as clearly shown in Fig. 1. This guide also serves to direct the grain inward to form the bundle.

The twisting` arrangement is as follows: II is a slotted wheel, the slotf" of which receives the wires after being doubled around the bundle, and twists up the ends by the revolving' motion of the wheel. This is the common way of twisting the wires in grain-binders. This slotted wheel has cogs, with which en ga-ges a gear-wheel, V. Another gear, W, lies below V on the same axis, and engages with it by a pawl and ratchet, so as to give motion to it in the forward turning, but disenga-ge from it in the back turning. A segment-gear, X, engages with V, having an arm, c', with which are connected toggles h1 h2 attached to rod Il that runs back to cam K, and is connected and operated in the same manner as rods S S. This forward-aiid-baclt motion gives a corresponding alternate motion tothe gears XW, but only aforward motion to the slotted wheel U an d gear-wheel V, owing to the interposed ratchetand-pawl arrangement before spoken of. The slotted wheel, by the gearing up ofthe parts, receives several revolutions by one movement of the arm I), and is so adjusted that its slot always comes in position for the wires at the extent of each stroke. \Vhen the twisting is accomplished, a cutter, Y, Fig. 3, pivoted at i and operated by therod S/ and cam L, passes across the slot, and divides the twist of the wire, and frees the bundle, while th e end of the wire with the twist on it is wound upon the secondary spool Z below the main spool. This spool winds up only a short length or section of the. end ofthe wire after the securing of each bun- (lle-just sufficient to draw the twist already formed down out of the slot of the wheel to give freedom to the twist of the next bundle. In fact, all the wire that winds upon this spool z is made up of short pieces occurring from the successive cutting of the twists, as but a single wire is used. In other words, the lower attachment of the wire is with spool z, while the upper spool N, which holds the surplus, lets it off a-s required, and spool z simpl v turns sufficiently to draw down the twisted part and keep it free from the operating devices. The movement of the spool z is accomplished by a pawl, 7c', engaging with teeth on its periphery, said pawl being attached to brace q, and rocking with it. The outer length of the wire, after passing around the bundle, is carried into the slot of the twisting-wheel by means ofthe striking of the end of point 0 of the curved arm M upon an inclined plane, p2, just within the mouth of the box R. The box R inclosing the twisting arrangement, the arms Q Q', the arm M with its comlecting parts, also the cams J, K, and L with their rods S, S, and P', all move laterally on the platform in order to ada-pt the action of said parts to long or short grain. The box It is adjusted by means of a rod, A, pivoted thereto, which connects with a slide, u', which rests on a way, o. This way has adn `justing-holes at proper distance apart, and the slide has a pawl, which engages thereon. The cams and connecting part-s simply slide upon the main shaft H, which has a feather, fw', Fig. S; and the cams are keyed in place. The curved arm M and adj uncts slide upon the shafts o p. To insure perfect control of the operatin g parts, the bevel-gear 1 is allowed to slide outward upon its shaft by means of a feather thereon, and is provided with a slot or hole, n', which receives or is forced over a pin, m', on the upright 02 by the pressure of a spring, q, placed against the wheel, as clearly shown in Fig. 9. This has the effect to sever the connection between the bevel-gear 1 and pinion 2. Then it is desired to again apply the power, the bevel l is forced back awa-y from the pin m and againstspring y by the short arm of lever r2, which has a cord or chain extending from the long arm to the operator, until it meshes with pinion 2, and, the gear 1 com- 1n encing its revolution directly this occurs, the hole a is carried beyond the pin m', which latter, by bearing against the face ofthe bevel l, insures the connection until the revolution is completed, and the hole again comes opposite and is forced over the pin by the force of the spring' behind.
